Lophodermium unciniae P.R. Johnst. 1989

PDD 46156 - holotype, PDD 49354, 49024, 49303, 49156, 49358 (IMI), 49359, 49357, 49355, 49356, 46119, 46155 (IMI).
Ascocarps and pycnidia developing in yellowish areas, often surrounded by broad, brown zone lines. Ascocarps 0.7-1.2 x 0.2-0.3 mm, oblong in outline with broadly rounded ends. Immature ascocarps with dark grey to black walls with narrow, pale zone along future line of opening. Mature ascocarps with black walls, paler zones at both ends of the longitudinal opening slit, sometimes with narrow, hyaline, fimbriate zone along edge of opening. Pycnidia 0.2 mm diam., initially concolorous with surrounding host tissue, becoming pale brown, immersed.

Ascocarps in vertical section intraepidermal, upper wall up to 20 µm wide, uniform in width across ascocarp, comprising dark brown, thick-walled, angular cells. Inside of upper wall near ascocarp opening lined with a layer of 10-20 x 2-3 µm cylindric cells. These cells mostly hyaline, becoming dark brown at apex. Lower wall 10-15 µm wide, of dark brown, thick-walled cells.

Paraphyses 1.5-2 µm diam., swelling to 2.5-4.5 µm diam. at apex, often branching 1-2 times 20-30 µm from apex, embedded in gel, extending 20-30 µm beyond asci. Asci 125-155 x 4.5-6.5 µm, cylindric, tapering to small, truncate apex, wall thickened near apex with broad, central pore, 8-spored. Ascospores 85-115 x 1-1.5 µm, 0-1 septate, with indistinct gelatinous sheath.

Pycnidia in vertical section intraepidermal. Upper wall absent or poorly developed. Lower wall comprising 2-3 layers of pale brown, thin-walled cells. Conidiogenous cells lining lower wall, 6.5-9 x 2.5-3.5 µm, hyaline, flask-shaped, sympodial. Conidia 3.5-4 x 0.8-1 µm, cylindric, hyaline, 0 septate.

Auckland, Coromandel, Taupo, Wellington, Buller, Westland.
Common on dead leaves of Uncinia spp., rare on Carex and Juncus.
Ascocarpi oblongi, atri, intraepidermales. Cellulae intra parietem superiorem, prope aperturam ascocarpi, cylindricae. Paraphysium apex ramosus, clavatus, 2.5-4.5 µm diam. Asci 125-155 x 4.5-6.5 µm, cylindrici, apicem versus decrescentes. Ascosporae 85-115 x 1-1.5 µm.

ETYMOLOGY: unciniae; refers to host substrate of holotype.

NOTES: See notes under L. hauturuanum.

COROMANDEL, Moehau, Te Hope Stream Tr., 200m, on Uncinia sp., coll. Johnston (R538), 28 Aug 1984 (PDD 46156).
